Not sure how you created a topic without a post, but check out this thread for the chat codes.

For the wiki link, you can usually just append the item name to the wiki search URL, e.g., http://wiki.guildwars2.com/index.php?search=Courage.

The wiki also accepts GW2’s chat links.

But you must remember to replace escape characters such as & with percent encoding.
